Car-truck.



vANIA.

To all whom. it may concern Be it known that I, \YALTER S. ADAMS, a citizen of the United States, and a resident of the city of Philadelphia, county of Philadelphia, and State of Pennsylvania. have invented certain new and useful Improvements in Ca-1'-Trucks, of which the following isa specification.

This application is a division of my copending application, Ser. No. 872,509. filed November 17th. 1914;.

" My invention relates to a bolster supporting means in car trucks wherein the bolster is'supported near it ends on a combination of leaf and coil sprmgs, this combination allowing the bolster to be carried true with-- out undue jar or Vibration.

The present invention also resides in certaln novel features of construction and combination of elements. which will be hereinafter described and further pointed out in the claims appended hereto. I

For-a more particular description of my invention, reference is to be had to the ac companying drawings, in which- Figure 1 is a side GIQXtltlOH of my improved bolster supporting arrangen'ient with ,portions of a truck being shown to illustrate its'application to a truck: Fig. 2 is a front elevation of the same, partly in section; and Fig. 3 is a side elevation, partly in section,

: of the spring arrangement for supporting a the bolster.

Throughout the yarioui views of the drawing, similar reference characters designate similar par s. i

As my invention may be applied to many kindsof trucks, I do not attempt to show ,any one in particular, but disclose a portion pf a truck which may be taken as t pical of --a number and I show no parts that are irrelevant to my improvements. I 'showYpor- 'These bearing blocksS are fixed inplace on the gusset plates 4 by bolts 10.

dies 12, which c'onnectthe lower ends of hangers.

Itach spindle 12 is made square'o'r of like I cross section at its outer ends so as to fit corresponding parts of the hangers. 11 and not turn therein. Between the hangers.

however, the spindle 12 is made circular in I cross section so as to receive and support a suitable bearing in a bracket- ].3, which is fixed b means of bolts 1 to a spring seat 15- and to angte bars 16 by rivets 17, the parts 13. 14, 15, 16 and 17 forming a spring plank. The. seats 15 hold the bands 18 of lower leaf springs 1 The bolster T is mounted on up,- per leaf springs 20, held together by bands 21. The leaf spring 20 is bent upwardly at 23 and the leaf spring 19 downwardly at 24 in like manner. Extending between the two widened portions thus formed, are the coil springs 1.4-4, carried by spring seats 26, each of said seats having projections 27 fitting perforations 28 in the leaf springs.

It is tobe noted that the parts 23 and 24 come together when a certain weight is inc-- posed upon the car and then the. balance of the weight is carried by the leaf springs 19 and 20. It is also to be noted that when the parts 23 and 21- come together, the operative length of the leaf springs is lessened and they thus become stronger and their resistcoil springs mounted between said leaf springs and portions of said leaf springs adapted to rest together when the coil springs are suiiiciently compressed.

In a truck of the class describedfa truck frame, hangers supported by said truck frame, transversely disposed leaf springs supported by said hangers. a bolster supported said leaf springs, coil springs mounted between said'leaf springs, said leaf springs being so'formed that portions of'the, same rest together and l mit the compress on of the coil springs.
